Kelsey Grammer, playing the hard-cursing, soul-crushing mayor in the Starz drama, cuts loose with a litany of NSFW expletives, but I think he favors the simple, classic F-word and its various iterations.

The video is bleepin' awesome. You can watch Kane spew more swear words when "Boss" airs new episodes at 8 p.m. CT Fridays on Starz. If you've missed what's happened so far in Season 2, Starz will broadcast a marathon of the season on its National Boss Day, Oct. 16, beginning at 9 a.m. You can catch-up on all episodes before the Season 2 finale at 8 p.m. Oct. 19.
